WATER-CLOSET VALVE.

SPECIFICATION forming part of Letters Patent No. 449,769, dated April 7,1891.

Application filed September 3, 1889. Serial No. 322,882. (No model.)

I r j M all whom/ at III/[b1] coll/007w:

Be it known that I, \VILLIAM II. ARD, of

Boston, in the county of Sulfolk and State of Massachusetts, haveinvented certain new and useful Improvements in Water-Closet Valves, ofwhich the following is a specification.

This invention has for its object to provide a valve for water-closetsupply-tanks having improved means by which it shall be retarded in itsclosing movement by an air-cushion and allowed to close at any desiredrate by the escape of the air forming said cushion through an adjustablevent or orifice.

The invention comprises the detail construction, combination, andarrangement of parts, substantially as hereinafter fully set forth, andparticularly pointed out in the claims.

Of the accompanying drawings, forming a part of this specification,Figure 1 represents a vertical sect-ion of my improved valve and a partof the bottom of a tank to which it is applied, the valve being closed.Fig. 1 represents a perspective view of the air-valve. Figs. 2 and 3represent similar views, the valve being raised, Fig. 2 showing theconditions when the valve is being raised, while Fig. 3 shows theconditions when the valve is descending. Figs. 4 an d 5 representsectional views of modifications.

The same letters of reference indicate the same parts in all thefigures.

In using the term valve in this specification it will be understood thatI refer to the part that is seated upon the outlet-pipe and directlycontrols the escape of water, while by the term air-valve I mean thevalve that admits air to the air cup or chamber.

In the drawings, a represents the bottom of a watercloset supply-tank,and b the outletpipe or fitting secured thereto in any suitable way andprovided with a seat 0 for the valve (Z. Said valve may be of anysuitable construction. In Figs. 1, 2, and 3, which I will firstdescribe, I have shown it made in one piece with the inverted cup orchamber 6, which contains the air-cushion, the valve being the lower endor mouth of said cup.

f represents the fixed part which constitutes the bottom of theair-chamber within the cup e, said part being a circular head or pistonsnugly fitting the interior of the cup (2 and connected by verticalstandards 2 2 with a screw-threaded ring 3, which is screwed into thevalve-seat or escape-pipe fitting. When the valve (Z and cup careraised, an air-space is formed between the fixed headfand the top of thecup 6, air being admitted to said space from a point above the water inthe tank through a pipe h, which is affixed to the cup and extendsupwardly, so that its upper end is above the highest level the water canattain in the tank. In the upper end of said pipe is an air-inlet '17,at the inner end of which is a valve-seat j.

70 represents the air-valve, which is located in the pipe h between theseatj and a fixed collar or support an, and is adapted to play betweensaid seat and collar. The air-valve is formed at its upper end to fitsaid seat and close the air-inlet when raised by air-pressure within thepipe. Said air-valve is provided with one or more grooves 7.;', (seeFig. 1,) which permit air to pass around the air-valve when the latterrests on the collar m. In the upper portion of the pipe 72 below theair-inlet, is a branch, in which is an air-outlet 0, having a screw P,which adjusts the size of the outlet-passage.

From the foregoing it will be seen that when the valve (l is closed, asshown in Fig. 1, the air-valve 7trests on the collar m and permits thepassage of air around it, so that when the valve d is being raised theair will enter at the inlet i and pass downwardly around the air-valve7.; through the pipe h into the cup e, as indicated by the arrows inFig. 2. Then the valve is released and commences to fall, the air-pressure raises the air-valve 7.; to the seat j, as shown in Fig. 3, thusclosing the airinlet 2', so that air can escape only through the outlet0, the air passing from the cup 8 through the pipe h to the air-outlet,as indicated by the arrows in Fig. 3. The valve d can therefore fallonly as fast as the air-cushion formed in the cup 6 by the raising ofthe valve is reduced by the escape of air through the outlet 0, and saidescape can be made as slow as may be desired by adjustment of the screw1).

In Figs. 1, 2, and 3 I show a stand or overf being the top of the cage.

flow pipe 1 attached to the cup 0, the latter having double walls,between which is a space 1', communicating with the stand-pipe. Theinner wall of the cup has ports 5 5-, through which water entering thestand-pipe will flow out into the discharge-pipe.

To limit the upward movement of the valve (1 and cup 6, I provide thefixed headf with an upwardly-proj ecting stud g, extending into the pipeh and provided within the latter with a head g, which, by engaging ashoulder g in the pipe 72 prevents the cup from being lifted above thehead f. Said stud is made tubular, so that air can pass through it, asindicated in the drawings. Any other suit able stop may be substitutedfor the stud.

In Fig. at I have shown a construction similar to that alreadydescribed, excepting that the cup is not provided with a stand-pipe, afixed stand-pipe q being connected with the outlet pipe or fitting atone side of the valve.

In Fig. 5 the cup is located above the water in the tank and attached toa rod a, passing through a fixed cross-bar '2; above the waterline. Thefixed partor headf, that constitutes the bottom of the air-space withinthe cup 0, is aifixed to said cross-bar. In this modification the valveis pivoted or loosely connected to the lower end of the rod '11 and theairvalve 7t is on the under side of the top of the cup. The air-outletmaybe arranged as previously described or in any other suitable manner.

The head f, the vertical standards 2 2, and the screw-threaded ring 3are cast in one piece and constitute what I term a cage, the head Theoutlet-fitting I) has an internal screw-thread within the valve-seat c,and the threaded ring of said cage is screwed into said shoulder, asshown. The cage is therefore within the circle of the valve-seat and iseasily attached to and removed from the outlet-fitting.

I claim 1. The combination, with the outlet-fitting, of the fixed partor head secured thereto and projecting upwardly therefrom, thecylindrical valve, the inverted cup secured thereto and located thereinand inclosiug said fixed part or head and having an upper pipe 71,provided with an inlet and an outlet at its upper end, substantially asset forth.

2. The combination, with the outlet-fitting, of the fixed part or headsecured thereto and projecting upwardly therefrom, the cylindrical valveseated at its lower end on said outlet-fitti n g, the inverted cupsecured to said valve and located therein and inelosing said fixed partor head, the upper pipe h, projecting from said cup and having upper andlower valve-seats in its upper end, and amovable or sliding air-inletvalve, substantially as set forth.

3. The combination, with the outlet-fitting, of the fixed part or headsecured thereto and projecting upwardly therefrom, the cylindrical valveseated at its lower end on said outlet-fittin g, the inverted cupsecured to said valve and located therein and inclosing said fixed partor head, the upper pipe 7L, projectin g from said head and having alower shoulder g and upper and lower valveseats in its upper end, themovable or sliding air-inlet valve, and the pipe g, projected from saidfixed part or head and having an upper enlarged on d located in saidpipe 71, and designed to engage said shoulder g", as set forth.

4. The combination of the valve, the inverted cup attached thereto andprovided with the upwardly-projecting pipe 7L, the air-inlet valve andthe adjustable air-outlet in the upper portion of said pipe, and thefixed head f, attached to the outlet-fixture and located in the invertedcup asabottoin for the air-chainber therein, and the fixed stud attachedto the head f and provided within the pipe 71. with a head orenlargement, whereby removal of the valve from the headf is prevented,as set forth.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, this 0th day of May, A. D. 1889.
